PARTA k = 2.000 N/m F = -kX M=0.125kg wood E 4 x(m) a 0.04 0.02 A 0.125kg mass is attached to a horizontal spring of spring constant k = 2 N/m and set into oscillation. Assume frictionless floor. What is the angular frequency of the vibration? 6 = - 4 radis How about the vibrating frequency fin Hz? f = -0.6306 = 2 The position of the mass is given as x = A cos (ot + ). With your calculated value of o, fill in the following table don't forget to set your calculator to "radian mode"). Each row represents a different oscillation with the same spring, pay attention to sign: A (m) v(m/s) a (m/s) t(s) 00 (rad) F(N) 0.03 En Diaz D00920030169 2.5 0.3 10.0384 0.1385 0.3199 0.2118 0.2 -0.04 0.06 D-05136 0.1 1-0.8672 1.36 0.4 0.04 0.3 1-0.64 1-0.08 -0.05 -0.25 0.1 X = AcOS (wt + Do).
